Royal Carribean's COVID Policy -- We strongly recommend that all guests 12 years of age and older be fully vaccinated before sailing. We will ask, but not require, that fully vaccinated guests provide documentation of vaccination before boarding (for example, a U.S. CDC vaccination card). A guest who cannot provide documentation of vaccination will be considered unvaccinated and must adhere to additional health protocols and undergo COVID-19 testing. Unvaccinated guests 12 and older will be responsible for covering the fees associated with these tests.
Basically, according to Florida law, they can't require that the cruiser show proof of vaccination. But, according to the cruiseline, if they don't show proof of vaccination, they have to follow CDC guidelines. Basically, it means that they should wear a mask when in public areas. To be fair, the cruise lines are between a rock and a hard place, but this is very close to separating the "good" citizens from the "bad" citizens. This is a very bad precedent. It's not a big step from separating the good Germans from the bad Jews. Either require that all guests and crew members be vaccinated or don't. You can't serve both groups at the same time.
